How To Beat A Beauty Without Killing
When fighting a beauty, be equipped with the neutralizer gun. After you hit Beauty with it, her psyche gauge will drop instead of her health. After her psyche gauge is completely down, she will be defeated.
Beating her this way rewards you with a mask with her face on it.
